【摘要】 本文研究了铁磁材料的晶粒度与巴克豪森噪声 (BN )强度、波形特征参数之间的关系 ,提出用波形半高宽的占空比 μ作为测量参数 ,能较好地表征晶粒度的大小。更多还原

【Abstract】 The paper studies the relationship between the grain size of ferromagnetic materal and Barkhausen Noise BN strength, characteristic parameters of BN wave. In the end, the paper proposes that u whick is half the height of wave peak is a good parameter to measure grain size.更多还原
